CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is a U.S. National Phase of International Patent Application No. PCT/JP2015/064488 filed on May 20, 2015, which claims priority benefit of Japanese Patent Application No. JP 2014-154713 filed in the Japan Patent Office on Jul. 30, 2014. Each of the above-referenced applications is hereby incorporated herein by reference in its entirety. 
     TECHNICAL FIELD 
     The present disclosure relates to a medical printer that prints on a roll sheet. 
     BACKGROUND ART 
     Printers are requested to have the performance and usability according to where and how the printers are used. It is also necessary for printers for medical use to have different performance and usability in accordance with situations such as medical care, examination, and other medical matters in which the printers are used. Speaking of performance, printers that print, for example, medical records have to have high-performance of printing fast. Printers for echography have to have such image quality that no light and shade are produced from rough surfaces of printing sheets and irregularity particular to the machines because the printers that print images resulting from echography allow states of affected areas and unborn children to be expressed in light and dark colors for diagnosis. Meanwhile, speaking of usability, printers have to be easily operated and space-saving, which namely means that the printers are not particular about where to be disposed upon use. 
     For example, a printer mounted and used on a cart  10  as illustrated in  FIG. 18  together with a medical examination device  15 , a keyboard  16 , and a display  17  is suitable as a printer that prints on a roll sheet that is a rolled long sheet, the cart  10  being can be moved by wheels  12  under a base  11 . Printers that print on a roll sheet can cut the sheet in accordance with a quantity of print. Moreover, such printers can efficiently accommodate a sheet, thereby being easy to downsize. 
     Printers that print on a roll sheet have to cut a part of the roll sheet on which the printers have already printed as the printers are outputting the roll sheet. If printers are equipped with an automatic cutting mechanism for automatically cutting a roll sheet, the printers become larger and cost more. Accordingly, there are also a large number of printers that adopt a manual cutting mechanism that allows users to cut a roll sheet by pulling the roll sheet in contact with a cutter blade. For example, Patent Literatures 1 and 2 disclose printers equipped with a manual cutting mechanism. The manual cutting mechanisms disclosed in Patent Literatures 1 and 2 each allow users to grasp a roll sheet ejected from the printer, to turn up the roll sheet in the opposite direction to the ejecting direction, and to pull the roll sheet in contact with the cutter blade in order to make a crack on the roll sheet and cut the roll sheet.

     DISCLOSURE OF INVENTION 
     Technical Problem 
     However, the printers disclosed in Patent Literatures 1 and 2 have a limited direction in which a roll sheet is pulled when the roll sheet is cut. Moreover, the printers are disposed in a limited place. Since small printers have no clearance for pulling down a roll sheet, a manual cutting mechanism is usually attached to the conveyance passage of a roll sheet such that the roll sheet is pulled up to be cut. However, supposing, for example, that a printer  18  is mounted on the cart  10  as illustrated in  FIG. 18 , the printer  18  can be disposed only on a shelf  14   b  or  14   c  under a table  14   a  on which the keyboard  16  is mounted in the example of  FIG. 18 . For example, when the printer  18  is disposed on the shelf  14   b , no clearance for pulling a roll sheet can be provided above the manual cutting mechanism so that it becomes difficult to cut the roll sheet. 
     It is also conceivable that a manual cutting mechanism is additionally attached to a lower face of conveyance passage of a printer such that a roll sheet can be pulled down to be cut. However, the roll sheet ejection port is generally a movable section that is opened and closed such that the printer accommodates a roll sheet. There is no providing a cutter blade to the movable section for structural safety reasons. 
     The present disclosure therefore proposes a novel and improved medical printer that can cut a roll sheet by pulling the roll sheet in any of the up direction and the down direction. 
     Solution to Problem 
     According to the present disclosure, there is provided a medical printer including: a main body that accommodates a roll sheet; a movable section including a front panel that covers a front face, the movable section being capable of opening and closing against the main body; a first cutting section provided on the movable section, and configured to cut the roll sheet ejected from an ejection port defined by the main body and the movable section; and a slide section configured to slide the front panel or the first cutting section in a radial direction with respect to a rotation center of the movable section in accordance with open and closed states of the movable section. 
     Advantageous Effects of Invention 
     According to the present disclosure as described above, there is provided a medical printer that can cut a roll sheet even if the roll sheet is pulled in any of the up direction and the down direction. Note that the effects described above are not necessarily limitative. With or in the place of the above effects, there may be achieved any one of the effects described in this specification or other effects that may be grasped from this specification.

&lt;1. First Embodiment&gt;
 
[1.1.Overall Configuration]
   

     First of all, with reference to  FIGS. 1 and 2 , the schematic configuration of a medical printer  100  according to a first embodiment of the present disclosure will be described.  FIG. 1  is an overall perspective view of the medical printer  100  according to the present embodiment.  FIG. 2  is an overall perspective view illustrating that a movable section  104  of the medical printer  100  according to the present embodiment is opened. The medical printer  100  will also be simply referred to as a printer  100  below. 
     The medical printer  100  according to the present embodiment is, for example, a thermal printer that prints images on a roll sheet, the images being generated on the basis of reception signals from a probe that is provided to an ultrasonic diagnostic device and is a medical examination device configured to generate and transmit ultrasound and receive ultrasound reflected in a living body. The present technology can be applied to not only the medical printer  100 , but also any printer including a manual cutting mechanism that allows users to cut a roll sheet. The medical printer  100  is considered to be mounted and used on the cart  10  as illustrated in  FIG. 18  like the printer  18 . 
     The medical printer  100  according to the present embodiment is considered to be a thermal printer, but the present disclosure is not limited to such an example. For example, the medical printer  100  may also be an inkjet printer. In this way, the present technology is applicable regardless of printer&#39;s printing type. Accordingly, the description about a printing function of the printer being omitted, a main body  102  of the printer  100  includes a print unit that prints on a roll sheet P. The material or the thickness of the roll sheet P is not particularly limited. For example, a thermal film having a thickness of approximately 100 μm may be used for the roll sheet P. 
     The medical printer  100  according to the present embodiment is, for example, a thermal printer that prints on the roll sheet P. As illustrated in  FIG. 1 , the housing of the medical printer  100  includes the main body  102  and the movable section  104  provided in a manner that the movable section  104  can be opened and closed with respect to the main body  102 . 
     The main body  102  is a case that accommodates a print unit (not illustrated) that prints on the roll sheet P. An accommodation section  150  that accommodates the roll sheet P is disposed on the face (which will be referred to as “main body front face”)  102   a  in the x-axis positive direction of the main body  102 , as illustrated in  FIG. 2 . The movable section  104  provided on the main body front face  102   a  is opened so that the roll sheet P can be accommodated in the accommodation section  150 . The main body front face  102   a  is also provided with an operation display section  140  including a power switch, an open button for opening the movable section  104 , and a lamp indicating the activity state of the printer  100 . The movable section  104  and the operation display section  140  are disposed together on the main body front face  102   a , which allows the printer  100  to be operated if nothing is placed in front of the main body front face  102   a  of the printer  100 . 
     The movable section  104  is a cover member provided on the main body front face  102   a  in a manner that the movable section  104  can be opened and closed with respect to the main body  102 , the movable section  104  being disposed to cover the accommodation section  150  for the roll sheet P in the main body  102 . The movable section  104  includes, for example, a bearing (not illustrated) that pivotably supports a shaft (not illustrated) provided on the bottom face side of the printer  100  and extending in the width direction (y direction). The bearing of the movable section  104  pivotably supports the shaft of the main body  102 , and a hinge is consequently formed. As illustrated in  FIG. 2 , the upper part side of the main body front face  102   a  of the movable section  104  can be configured to move with respect to the main body  102 . 
     A part of an upper end  104   b  of the movable section  104  is recessed in the height direction (z direction), thereby forming a recess  104   d . The recess  104   d  makes a slight gap between the upper end  104   b  of the movable section  104  and a lower end  102   b  of the main body front face  102   a , the lower end  102   b  facing the upper end  104   b . The gap functions as an ejection port  110 , from which the roll sheet P is conveyed along the conveyance passage inside the printer  100  and ejected. The ejection port  110  includes a manual cutting mechanism for cutting the ejected roll sheet P. 
     After the print unit prints on the roll sheet P accommodated in the accommodation section  150 , the roll sheet P is conveyed along the conveyance passage inside the printer  100  and ejected from the ejection port  110 . A conveyor roller  160  that conveys the roll sheet P to the ejection port  110  is provided in front of the ejection port  110  as illustrated in  FIG. 2 . 
     [1.2. Manual Cutting Mechanism] 
     The printer  100  according to the present embodiment includes, as a manual cutting mechanism, an upper cutting section (second cutting section)  120  at the lower end  102   b  of the main body front face  102   a , and a lower cutting section  130  (first cutting section)  130  in the recess  104   d  at the upper end  104   b  of the movable section  104 . The following describes the manual cutting mechanism provided on the medical printer  100  according to the present embodiment on the basis of  FIGS. 3 to 9 .  FIG. 3  is a front view of the movable section  104 ,  FIG. 4  is a back view of the movable section  104 , and  FIG. 5  is a top view of the movable section  104 .  FIG. 6  is a partial cross-sectional view corresponding to the A-A cross section of  FIG. 3  and illustrating a closed state in which the movable section  104  is closed against the main body  102 , and illustrates that the upper cutting section  120  is cutting the roll sheet P.  FIG. 7  is the same partial cross-sectional view as  FIG. 6 , and illustrates that the lower cutting section  130  is cutting the roll sheet P.  FIG. 8  is a partial cross-sectional view illustrating that the movable section  104  is partially opened.  FIG. 9  is a partial cross-sectional view illustrating an open state in which the movable section  104  is fully opened. 
     (1) Upper Cutting Section (Second Cutting Section) 
     The upper cutting section  120  is a manual cutting mechanism used when the roll sheet P ejected from the ejection port  110  is pulled up to be cut as illustrated in  FIG. 6 . The upper cutting section  120  includes a cutter blade extending in the width direction (y direction) of the ejection port  110 . The cutter blade can be made of metal or resin such as plastic. The part of the cutter blade in contact with the roll sheet P is formed in a zigzag or a sharp shape as illustrated in  FIG. 1  because it is easier to make a crack in the roll sheet P. The upper cutting section  120  does not have to be necessarily provided in the present embodiment. 
     (2) Lower Cutting Section (First Cutting Section) 
     The lower cutting section  130  is a manual cutting mechanism used when the ejected roll sheet P is pulled down to be cut. The lower cutting section  130  according to the present embodiment is provided on the movable section  104 , and pivots with respect to the main body  102  along with the movable section  104 . The movable section  104  includes a front panel  104 A that covers the front face of the printer  100 , and a door metal part  104 B, and is configured to pivot on a rotating shaft  104 C as the rotation center. In the present embodiment, the door metal part  104 B can pivot only on the rotating shaft  104 C. However, the front panel  104 A is configured to be slightly movable in the radial direction in addition to pivoting on the rotating shaft  104 C. The lower cutting section  130  is fixed to the door metal part  104 B as illustrated in  FIG. 6 . 
     The lower cutting section  130  includes a cutter blade  132  that is a member for making a crack in the roll sheet P, and a fixation section  134  that is provided on the opposite side to the cutting edge of the cutter blade  132  and fixed to the door metal part  104 B. 
     The cutter blade  132  is provided along the width direction (y direction) of the ejection port  110  similarly to the upper cutting section  120 . When the movable section  104  enters the closed state with respect to the main body  102 , a cutting edge  132   a  of the cutter blade  132  is exposed from the ejection port  110 . If the cutter blade  132  is inclined in this state in a manner that the height position (the position in the z-axis direction) grows higher from the main body side to the cutting edge  132   a , the roll sheet P can be smoothly ejected. If the cutting edge  132   a  is substantially vertical to the conveyance direction of the roll sheet P, the roll sheet P abuts the cutter blade  132   a  inside the main body  102  upon being pulled into the printer  100 . As a result, the roll sheet P is not ejected from the ejection port  110  in some cases. Accordingly, if the cutting edge  132   a  of the cutter blade  132  is inclined to a vertical face (i.e., y-z plane) of the movable section  104  along the conveyance direction of the roll sheet P, the roll sheet P can be smoothly ejected. The cutter blade  132  can be made of metal or resin such as plastic. The part of the cutter blade  132  in contact with the roll sheet P is formed in a zigzag or a sharp shape because it is easier to make a crack in the roll sheet P. 
     The fixation section  134  is a member for fixing the cutter blade  132  to the door metal part  104 B, and may be integrated with the cutter blade  132 , for example, as illustrated in  FIGS. 6 and 7 . The fixation section  134  has the cross section of the z-x plane shaped like L to support, for example, the shape of the door metal part  104 B having the L-shaped cross section of the x-z plane. The end of the horizontal portion of the fixation section  134  is coupled to the end opposite to the cutting edge  132   a  of the cutter blade  132 . The inclination angle of the cutter blade  132  to the horizontal portion of the fixation section  134  may be set, for example, between approximately 20 to 30°. This can smoothly eject the roll sheet P, and easily make a crack at a cutting position of the roll sheet P. 
     (3) Slide Section 
     In the printer  100  according to the present embodiment, the front panel  104 A is configured to be movable with respect to the door metal part  104 B in the radial direction of the rotating shaft  104 C in accordance with the open and closed states of the movable section  104 . This sliding operation of the front panel  104 A exposes the cutter blade  132  of the lower cutting section  130  from the ejection port  110  as illustrated in  FIGS. 6 and 7  and allows the roll sheet P to be cut when the movable section  104  is in the closed state. Meanwhile, once the movable section  104  enters the open state, the front panel  104 A is slid outward in the radial direction and the cutter blade  132  is covered by the front panel  104 A as illustrated in  FIGS. 8 and 9 . That is to say, once the front panel  104 A is opened, the cutter blade  132  is covered to prevent a user from touching the cutter blade  132  and to keep the safety. 
     The slide section according to the present embodiment includes a rib  192  provided on an inner face  104   c  of the front panel  104 A, and a cam  194  provided on the main body  102  to abut the rib  192 . 
     The rib  192  is a plate member that projects from the inner face  104   c  of the front panel  104 A to the inside of the main body  102  as illustrated in  FIG. 6 . The rib  192  is shaped substantially triangular and has an abutting face  192   a  having the lower part side substantially parallel to a bottom face  102   c  of the main body  102  as seen, for example, from the y-axis direction. The rib  192  includes two ribs  192 A and  192 B that are provided, for example, on both sides of the inner face  104   c  of the front panel  104 A in the width direction as illustrated in  FIG. 4 . 
     The cam  194  is fixed onto the inner side of the bottom face  102   c  of the main body  102  as illustrated in  FIG. 6 . The cam  194  includes two cams provided in association with the ribs  192 A and  192 B. The cam  194  has a first face  194   a  having the upper part side substantially parallel to the bottom face  102   c  of the main body  102  as seen, for example, from the y-axis direction, and a second face  194   b  that is arc-shaped from the end of the first face  194   a  on the front panel  104 A side. 
     The abutting face  192   a  of the rib  192  is in contact with the first face  194   a  and the second face  194   b  of the cam  194 . The abutting face  192   a  of the rib  192  moves along the first face  194   a  and the second face  194   b  of the cam  194  in accordance with the opening and closing of the movable section  104 . 
     First of all, when the movable section  104  is in the closed state, the abutting face  192   a  of the rib  192  abuts the first face  194   a  of the cam  194  as illustrated in  FIGS. 6 and 7 . Pivoting the movable section  104  to open the movable section  104  moves the abutting face  192   a  of the rib  192  to the front panel  104 A side along the first face  194   a  of the cam  194 , and then moves the abutting face  192   a  from the first face  194   a  of the cam  194  to the second face  194   b  as illustrated in  FIG. 8 . At this time, the rib  192  is slid outward in the radial direction of the rotating shaft  104 C. Meanwhile, the position of the lower cutting section  130  does not change. The cutter blade  132  is thus covered by the front panel  104 A, and is not exposed. 
     The abutting face  192   a  of the rib  192  comes into contact with the different faces of the cam  194  in this way, thereby changing the moving direction of the rib  192 . This slides the front panel  104 A, which moves along with the rib  192 , and changes the position in the radial direction of the rotating shaft  104 C. The shape of the cam  194  is decided as appropriate in accordance with the open and closed positions at which the cutter blade  132  is desired to be covered with the front panel  104 A. For example, when the movable section  104  is opened by a predetermined angle such as approximately 10 to 20° from the closed state in which the movable section  104  is completely closed, the abutting face  192   a  of the rib  192  may move from the first face  194   a  of the cam  194  to the second face  194   b.    
     Further opening the movable section  104  moves the abutting face  192   a  of the rib  192  along the second face  194   b  of the cam  194 . When the movable section  104  enters the open state in which the movable section  104  is completely opened, the cutter blade  132  is accommodated in the front panel  104 A as illustrated in  FIG. 9 . 
     Meanwhile, when the movable section  104  transitions to the closed state illustrated in  FIGS. 6 and 7  from the open state illustrated in  FIG. 9 , the movement is opposed to what has been described above. Pushing and closing the front panel  104 A in the open state against the main body  102  side moves the abutting face  192   a  of the rib  192  along the second face  194   b  of the cam  194 , and then to the first face  194   a . On this occasion, the front panel  104 A is slid toward the center in the radial direction of the rotating shaft  104 C. When the movable section  104  enters the closed state, the front panel  104 A fits with the main body front face  102   a  of the main body  102  and the front panel  104 A remains pushed down. This exposes the cutter blade  132  and allows the roll sheet P to be cut when the front panel  104 A is in the closed state. 
     [1.3. Cutting Roll Sheet] 
       FIGS. 6 and 7  illustrate methods for cutting the roll sheet P, the methods being performed by the upper cutting section  120  and the lower cutting section  130 , which are manual cutting mechanisms of the medical printer  100  according to the present embodiment.  FIGS. 6 and 7  illustrate the state of the roll sheet P, which is conveyed along the conveyance passage inside the printer  100  after the print unit prints on the roll sheet P accommodated in the accommodation unit  150 . The roll sheet P conveyed from the print unit passes through between the conveyance roller  160  and a guide member  170  so that the conveyance speed and the conveyance quantity of the roll sheet P are adjusted. Only the printed portion is ejected from the ejection port  110 . 
     First of all, as illustrated in  FIG. 6 , the roll sheet P ejected from the ejection port  110  is pulled up, and the upper cutting section  120  cuts the roll sheet P. When a user grasps the roll sheet P and pulled it up (z-axis positive direction), the roll sheet P abuts the tip of the upper cutting section  120  at the cutting position. When the user further pulls up one of the ends of the roll sheet P in the width direction, the upper cutting section  120  makes a crack in the roll sheet P at the end. When the user positions the cracked part at the cutting edge of the upper cutting section  120  and pulls up the roll sheet P toward the other end, the roll sheet P has continuous cracks and is finally cut away. Since the whole of the upper cutting section  120  is made of a cutter blade, the roll sheet P can be easily cut and a desired cross section can be obtained. 
     Meanwhile, as illustrated in  FIG. 7 , the roll sheet P ejected from the ejection port  110  is pulled down, and the lower cutting section  130  cuts the roll sheet P. When a user grasps the roll sheet P and pulls it down (z axis negative direction), the roll sheet P abuts the cutting edge  132   a  of the cutter blades  132  of the lower cutting section  130  at a cutting position. When the user positions the cracked part at the cutting edge  132   a  of the lower cutting section  130  and pulls down the roll sheet P toward the other end, the roll sheet P has continuous cracks and is finally cut away. Since the whole of the lower cutting section  130  is also made of a cutter blade, the roll sheet P can be easily cut and a desired cross section can be obtained. 
     As described above, since the medical printer  100  according to the present embodiment includes manual cutting mechanisms for cutting the roll sheet P at the upper and lower parts of the ejection port  110 , from which the roll sheet P is ejected, the roll sheet P can be pulled and cut in any of the up direction and the down direction. Thus, for example, when the printer  100  is positioned on any one of the shelves  14   b  and  14   c  of the cart  10  as illustrated in  FIG. 18 , it is possible to pull and cut the roll sheet P in a direction in which a clearance is provided. 
     &lt;2. Second Embodiment&gt; 
     Next, the configuration of the sliding configuration of a printer  200  according to a second embodiment of the present disclosure will be described on the basis of  FIGS. 10 and 11 .  FIG. 10  is a partial cross-sectional view corresponding to the A-A cross section of  FIG. 3  and illustrating the closed state in which the movable section  104  is closed against the main body  102 , and illustrates that the upper cutting section  120  is cutting the roll sheet P.  FIG. 11  is a partial cross-sectional view illustrating the open state in which the movable section  104  is fully opened. 
     The printer  200  according to the present embodiment is different from the printer  100  according to the first embodiment in the configuration of the slide section that slides the front panel  104 A in accordance with the open and closed states of the movable section  104 . That is to say, the printer  200  according to the present embodiment has a protrusion  202  provided on the bottom face  102   c  of the main body  102  instead of the rib  192  and the cam  194  according to the first embodiment. The following describes the configuration of the slide section of the printer  200  according to the present embodiment and an advantageous effect thereof on the basis of  FIGS. 10 and 11 . Since each section of the printer  200  has a similar configuration to the configuration described in the first embodiment except for the protrusion  202 , the detailed description will be omitted here. 
     [2.1. Protrusion] 
     The protrusion  202 , which is a slide section that slides the front panel  104 A of the movable section  104 , is provided on the outer front side of the bottom face  102   c  of the main body  102  as illustrated in  FIG. 10 . The protrusion  202  is provided at the position at which the protrusion  202  abuts a lower face  104   f  of the pivoting front panel  104 A when the movable section  104  is in the open state. As long as the protrusion  202  is provided at least partially in the width direction (y-axis direction), the protrusion  202  may be, for example, extended over the entire width, the two protrusions  202  may be provided near both ends, or the single protrusion  202  may be provided near the center. The protrusion  202  is, for example, made of the same material as that of the main body  102 . 
     [2.2. Front Panel Slid by Protrusion] 
     In the printer  200  according to the present embodiment, the front panel  104 A is configured to be movable with respect to the door metal part  104 B in the radial direction of the rotating shaft  104 C in accordance with the open and closed states of the movable section  104 . This sliding operation of the front panel  104 A exposes the cutter blade  132  of the lower cutting section  130  from the ejection port  110  as illustrated in  FIG. 10  and allows the roll sheet P to be cut when the movable section  104  is in the closed state. Meanwhile, once the movable section  104  enters the open state, the front panel  104 A is slid outward in the radial direction and the cutter blade  132  is covered by the front panel  104 A as illustrated in  FIG. 11 . That is to say, once the front panel  104 A is opened, the cutter blade  132  is covered to prevent a user from touching the cutter blade  132  and to keep the safety. 
     First of all, when the movable section  104  is in the closed state, the cutting edge  132   a  of the cutter blade  132  of the lower cutting section  130  is exposed from an opening  104   e  of the front panel  104 A as illustrated in  FIG. 10 . The roll sheet P can be thus cut with the cutter blade  132  of the lower cutting section  130 . 
     Pivoting the movable section  104  from the closed state to open the movable section  104  rotates the movable section  104  around the rotating shaft  104 C. The lower face  104   f  of the front panel  104 A then abuts the protrusion  202  provided on the main body  102  as illustrated in  FIG. 11 . At this time, the front panel  104 A is slid outward in the radial direction of the rotating shaft  104 C. Meanwhile, the position of the lower cutting section  130  does not change. The cutter blade  132  is thus covered by the front panel  104 A, and is not exposed. It is adjusted as appropriate how much the protrusion  202  slides the front panel  104 A, in a manner that the cutting edge  132   a  of the cutter blade  132  is hidden when the front panel  104 A is pushed up by the protrusion  202 . 
     Meanwhile, when the movable section  104  transitions to the closed state illustrated in  FIG. 10  from the open state illustrated in  FIG. 11 , the movement is opposed to what has been described above. Pushing and closing the front panel  104 A in the open state against the main body  102  side pivots and slides the front panel  104 A toward the center in the radial direction of the rotating shaft  104 C as much as the protrusion  202  has slid the front panel  104 A. When the movable section  104  enters the closed state, the front panel  104 A fits with the main body front face  102   a  of the main body  102  and the front panel  104 A remains pushed down. This exposes the cutter blade  132  and allows the roll sheet P to be cut when the front panel  104 A is in the closed state. 
     The configuration of the protrusion  202 , which is a slide section of the printer  200  according to the second embodiment of the present disclosure, and an advantageous effect thereof have been described so far. In the present embodiment, the protrusion  202  provided on the bottom face  102   c  of the main body  102  slides the front panel  104 A in the radial direction of the rotating shaft  104 C in accordance with the open and closed states of the movable section  104 . This exposes the cutter blade  132  of the lower cutting section  130  and allows the roll sheep P to be cut when the movable section  104  is in the closed state. The front panel  104 A is slid in the process of making the movable section  104  transition from the closed state to the open state, covering the cutter blade  132  with the front panel  104 A. Even when the movable section  104  is in the open state, a user can thus, for example, replace the roll sheep P safely. 
     &lt;3. Third Embodiment&gt; 
     Next, the configuration of the sliding configuration of a printer  300  according to a third embodiment of the present disclosure will be described on the basis of  FIGS. 12 to 14 .  FIG. 12  is a partial cross-sectional view corresponding to the A-A cross section of  FIG. 3  and illustrating the closed state in which the movable section  104  is closed against the main body  102 , and illustrates that the upper cutting section  120  is cutting the roll sheet P.  FIG. 13  is a partial cross-sectional view illustrating that the movable section  104  is partially opened.  FIG. 14  is a partial cross-sectional view illustrating an open state in which the movable section  104  is fully opened. 
     The printer  300  according to the present embodiment is different from the printer  100  according to the first embodiment and the printer  200  according to the second embodiment in that a lower cutting section  330  is slid in accordance with the open and closed states of the movable section  104 . The following describes the configuration of the slide section of the printer  300  according to the present embodiment and an advantageous effect thereof. Since each section of the printer  300  other than the lower cutting section  330  and a guide section  310  for sliding the lower cutting section  330  has a similar configuration to the configuration described in the first embodiment, the detailed description will be omitted here. 
     [3.1. Configuration of Lower Cutting Section] 
     The lower cutting section  330  of the printer  300  according to the present embodiment includes a cutter blade  332 , a coupling section  334  that couples a cutter blade  322  and a slider  336 , the slider  336  that slides along the guide section  310  as illustrated in  FIG. 12 . The cutter blade  332  is configured similarly to the cutter blade  132  according to the first embodiment. In the present embodiment, the cutter blade  332  slides in the radial direction of the rating shaft  104 C while the slider  336  slides along the guide section  310  in accordance with the open and closed states of the movable section  104 . 
     The guide section  310  is provided, for example, on the inner face of the side face (the face in the y-axis direction) of the main body  102 , and is formed to allow the slider  336  to slide between two guides  312  and  314  as illustrated in  FIG. 12 . The guides  312  and  314  are, for example, made of the same material as that of the main body  102 . 
     [3.2. Sliding Cutter Blade] 
     In the printer  300  according to the present embodiment, the lower cutting section  330  is configured to be movable with respect to the front panel  104 A in the radial direction of the rotating shaft  104 C in accordance with the open and closed states of the movable section  104 . This sliding operation of the lower cutting section  330  exposes the cutter blade  332  of the lower cutting section  330  from the ejection port  110  as illustrated in  FIG. 12  and allows the roll sheet P to be cut when the movable section  104  is in the closed state. Meanwhile, once the movable section  104  enters the open state, the cutter blade  332  is slid toward the rotation center in the radial direction as illustrated in  FIG. 14  and the cutter blade  332  is accommodated in the front panel  104 A and covered by the front panel  104 A. That is to say, once the front panel  104 A is opened, the cutter blade  332  is covered by the front panel  104 A to prevent a user from touching the cutter blade  332  and to keep the safety. 
     First of all, when the movable section  104  is in the closed state, the cutting edge  332   a  of the cutter blade  332  of the lower cutting section  330  is exposed from the opening  104   e  of the front panel  104 A as illustrated in  FIG. 12 . The roll sheet P can be thus cut with the cutter blade  332  of the lower cutting section  330 . 
     Pivoting the movable section  104  from the closed state to open the movable section  104  rotates the movable section  104  around the rotating shaft  104 C. The slider  336  moves along the guide section  310  counterclockwise in the middle state between the open state and the closed state as illustrated in  FIG. 13 , thereby sliding the cutter blade  332  toward the rotation center of the rotating shaft  104 C. Once the front panel  104 A completely opens and enters the open state as illustrated in  FIG. 14 , the cutter blade  332  is slid the most toward the rotation center in the radial direction of the rotating shaft  104 C, and accommodated in the opening  104   e  of the front panel  104 A. The position of the front panel  104 A does not change. The cutter blade  132  is covered by the front panel  104 A in this way, and is not exposed. 
     Meanwhile, when the movable section  104  transitions to the closed state illustrated in  FIG. 12  from the open state illustrated in  FIG. 14 , the movement is opposed to what has been described above. Pushing and closing the front panel  104 A in the open state against the main body  102  side pivots and moves the slider  336  of the lower cutting section  330  clockwise along the guide section  310 . At this time, the cutter blade  332  is gradually slid outward in the radial direction of the rotating shaft  104 C. When the movable section  104  enters the closed state and the front panel  104 A fits with the main body front face  102   a  of the main body  102 , the cutter blade  332  is exposed from the opening  104   e  of the front panel  104 A. This exposes the cutter blade  332  and allows the roll sheet P to be cut when the front panel  104 A is in the closed state. 
     The configuration of the lower cutting section  330  of the printer  300  according to the third embodiment of the present disclosure and an advantageous effect thereof have been described so far. In the present embodiment, the lower cutting section  330  is configured to be slidable in the radial direction of the rotating shaft  104 C in accordance with the open and closed states of the movable section  104 . This exposes the cutter blade  332  of the lower cutting section  330  and allows the roll sheep P to be cut when the movable section  104  is in the closed state. The lower cutting section  330  is slid in the process of making the movable section  104  transition from the closed state to the open state. When the movable section  104  enters the open state, the cutter blade  332  is accommodated in the front panel  104 A and covered by the front panel  104 A. Even when the movable section  104  is in the open state, a user can thus, for example, replace the roll sheep P safely. 
     &lt;4. Fourth Embodiment&gt; 
     Next, the configuration of the sliding configuration of a printer  400  according to a fourth embodiment of the present disclosure will be described on the basis of  FIGS. 15 to 17 .  FIG. 15  is a partial cross-sectional view corresponding to the A-A cross section of  FIG. 3  and illustrating the closed state in which the movable section  104  is closed against the main body  102 , and illustrates that the upper cutting section  120  is cutting the roll sheet P.  FIG. 16  is a partial cross-sectional view illustrating that the movable section  104  is partially opened.  FIG. 17  is a partial cross-sectional view illustrating an open state in which the movable section  104  is fully opened. 
     The printer  400  according to the present embodiment is configured to have a lower cutting section  430  slide in accordance with the open and closed states of the movable section  104  similarly to the third embodiment. The printer  400  is different from the printer  300  according to the third embodiment in that the lower cutting section  430  is slid by spring action in the radial direction of the rotating shaft  104 C. The following describes the configuration of the slide section of the printer  400  according to the present embodiment and an advantageous effect thereof. Since each section of the printer  400  other than the lower cutting section  430  and a guide section  410  for sliding the lower cutting section  430  has a similar configuration to the configuration described in the third embodiment, the detailed description will be omitted here. 
     [4.1. Configuration of Lower Cutting Section] 
     The lower cutting section  430  of the printer  400  according to the present embodiment includes a cutter blade  432 , a coupling section  434  that couples the cutter blade  432  and a slider  436 , the slider  436  that slides along the guide section  410  similarly to the third embodiment as illustrated in  FIG. 15 . The cutter blade  432  is configured similarly to the cutter blade  132  according to the first embodiment. In the present embodiment, the cutter blade  432  slides in the radial direction of the rating shaft  104 C while the slider  436  slides along the guide section  410  in accordance with the open and closed states of the movable section  104 . 
     The guide section  410  is provided, for example, on the inner face of the side face (the face in the y-axis direction) of the main body  102 , and is formed as a cam as illustrated in  FIG. 15 . The guide section  410  has a first face  412  having the upper part side substantially parallel to the bottom face  102   c  of the main body  102  as seen, for example, from the y-axis direction, and a second face  414  that is arc-shaped from the end of the first face  412  on the front panel  104 A side. The slider  436  of the lower cutting section  430  is in contact with the first face  412  and the second face  414  of the guide section  410 . The slider  436  moves along the first face  412  and the second face  414  of the guide section  410  in accordance with the opening and closing of the movable section  104 . 
     Tension is added to the cutter blade  432  of the lower cutting section  430  according to the present embodiment by a spring member  440  that is provided to extend when the movable section  104  is in the closed state. The spring member  440  may be, for example, an extension spring that adds force in the pulling direction. A fixed end  442  of the spring member  440  is fixed to a projection provided on the coupling section  434  of the lower cutting section  430 . Meanwhile, a hook section  444  of the spring member  440  is hooked on the door metal part  104 B. 
     [4.2. Sliding Cutter Blade] 
     In the printer  400  according to the present embodiment, the lower cutting section  430  is configured to be movable with respect to the front panel  104 A in the radial direction of the rotating shaft  104 C in accordance with the open and closed states of the movable section  104 . This sliding operation of the lower cutting section  430  exposes the cutter blade  432  of the lower cutting section  430  from the ejection port  110  as illustrated in  FIG. 15  and allows the roll sheet P to be cut when the movable section  104  is in the closed state. Meanwhile, once the movable section  104  enters the open state, the cutter blade  432  is slid toward the rotation center in the radial direction and the cutter blade  432  is accommodated in the front panel  104 A as illustrated in  FIG. 17 . That is to say, once the front panel  104 A is opened, the cutter blade  432  is covered by the front panel  104 A to prevent a user from touching the cutter blade  432  and to keep the safety. 
     First of all, when the movable section  104  is in the closed state, the cutting edge  432   a  of the cutter blade  432  of the lower cutting section  430  is exposed from the opening  104   e  of the front panel  104 A as illustrated in  FIG. 15 . The roll sheet P can be thus cut with the cutter blade  432  of the lower cutting section  430 . At this time, the spring member  440  extends to keep force for pulling the cutter blade  432  toward the rotation center of the rotating shaft  104 C, but the tension of the spring member  440  does not act on the cutter blade  432  while the slider  436  is in contact with the first face  412  of the guide section  410 . 
     Pivoting the movable section  104  from the closed state to open the movable section  104  rotates the movable section  104  around the rotating shaft  104 C. Once the slider  336  begins to move from the first face  412  of the guide section  410  along the second face  414  in the middle state between the open state and the closed state as illustrated in  FIG. 16 , the tension of the spring member  440  is applied to the cutter blade  432 , thereby sliding the cutter blade  432  toward the rotation center of the rotating shaft  104 C. This causes the cutter blade  432  to be accommodated in the front panel  104 A, and the cutter blade  432  is not exposed. 
     Once the front panel  104 A completely opens and enters the open state as illustrated in  FIG. 17 , the cutter blade  432  is slid the most toward the rotation center in the radial direction of the rotating shaft  104 C, and accommodated in the opening  104   e  of the front panel  104 A. The position of the front panel  104 A does not change. The cutter blade  132  is covered by the front panel  104 A in this way, and is not exposed. 
     Meanwhile, when the movable section  104  transitions to the closed state illustrated in  FIG. 15  from the open state illustrated in  FIG. 17 , the movement is opposed to what has been described above. Pushing and closing the front panel  104 A in the open state against the main body  102  side pivots and moves the slider  436  of the lower cutting section  430  clockwise along the second face  414  of the guide section  410 . At this time, the cutter blade  432  is gradually slid outward in the radial direction of the rotating shaft  104 C. Once the slider  436  moves from the second face  414  of the guide section  410  to the first face  412 , the spring member  440  extends. When the movable section  104  enters the closed state and the front panel  104 A fits with the main body front face  102   a  of the main body  102 , the cutter blade  432  is exposed from the opening  104   e  of the front panel  104 A. This exposes the cutter blade  332  and allows the roll sheet P to be cut when the front panel  104 A is in the closed state. At this time, the spring member  440  remains extended. 
     The configuration of the lower cutting section  430  of the printer  400  according to the fourth embodiment of the present disclosure and an advantageous effect thereof have been described so far. In the present embodiment, the lower cutting section  430  is configured to be slidable in the radial direction of the rotating shaft  104 C in accordance with the open and closed states of the movable section  104 . This exposes the cutter blade  432  of the lower cutting section  430  and allows the roll sheep P to be cut when the movable section  104  is in the closed state. The lower cutting section  430  receives the tension of the spring member  440  and is slid in the process of making the movable section  104  transition from the closed state to the open state. Meanwhile, when the movable section  104  enters the open state, the cutter blade  432  is accommodated in the front panel  104 A and covered by the front panel  104 A. Even when the movable section  104  is in the open state, a user can thus, for example, replace the roll sheep P safely. 
     The preferred embodiment(s) of the present disclosure has/have been described above with reference to the accompanying drawings, whilst the present disclosure is not limited to the above examples. A person skilled in the art may find various alterations and modifications within the scope of the appended claims, and it should be understood that they will naturally come under the technical scope of the present disclosure. 
     For example, in the above-described embodiments, the cutter blades of the first cutting section and the second cutting section are configured with a single member that extends in the width direction (y direction) of the ejection port  110 .
