Recording and/or reproducing apparatus

Abstract: A recording and/or reproducing apparatus comprises a display panel (47) which is disposed at such a position as not to face a cassette pressing member (28A,28B,44) between a lid (20) and a holder (22), thereby, it becomes possible to provide display portions by making effective use of a space defined between the lid and holder.

Description: This invention relates to a recording and/or reproducing apparatus, and more particularly to be applicable to a digital audio tape recorder for example. Conventionally, one known form of magnetic recording and/or reproducing apparatus (referred to as a digital audio tape recorder hereinafter) is adapted to convert an audio signal into a digital signal and to record it onto oblique tracks on a magnetic tape in sequence. If such a digital audio tape recorder could be made small in size and driven by means of a battery, it might become possible to enjoy music carrying the portable digital audio tape recorder as required and to improve its usefulness. Thereupon, for example if a display portion could be formed from a liquid-crystal display board so that a residual amount of a tape, the operation mode and the like can be confirmed via the display portion, this would be a convenience. JP-A-57-109,103 and JP-A-57-109,104 disclose tape recorders with display panels included in the cassette holder lid. Though forming the display portion in that way would assist in reducing the size of the apparatus, the operating elements are not easy to reduce in size without impeding the ease of operation of the machine. Instead of making the operation members smaller in size, it may also be thought possible to make the display board smaller in size. But, it is apprehended that it become inconvenient to look at a smaller display board. As a result, it is difficult to make the digital audio tape recorder smaller. In view of the foregoing, an object of this invention is to provide a small recording and/or reproducing apparatus equipped with a display portion. According to the present invention there is provided a recording and/or reproducing apparatus in which, in use a cassette is mounted, comprising: a holder for holding said cassette covered by a lid; cassette pressing means for pressing said cassette towards a predetermined position; and a display panel, disposed between said holder and said lid; characterised in that: said cassette pressing means is disposed on the lid side surface of said holder; and said display panel is at a position where it is not covered by said cassette pressing means but is covered by a window within the space between said lid and said holder. Other, optional features of the invention are defined in the sub-claims. Since the display panel is disposed at such a position as not to face the cassette pressing means between the lid and the holder, it becomes possible to make effective use of a space between the lid and the holder so as to dispose the display panel effectively and as a result to make the entire configuration smaller and thinner by that disposition. The invention will be further described by way of non-limitative example with reference to the accompanying drawings, in which:- Figure 1 is a perspective view showing digital audio tape recorder as one embodiment of the present invention; Figure 2 is a perspective view showing a detailed construction of the digital audio tape recorder; Figure 3 is a plan view showing a cassette tape; and Figure 4 is a plan view showing a display panel. Preferred embodiments of this invention will be described with reference to the accompanying drawings: In Figure 1, the symbol 1 designates a digital audio tape recorder which is adapted to be driven by means of a battery electrically connected to the rear thereof. Thereby, the digital audio tape recorder 1 is adapted to present a pleasant music and the like even though it is carried to such a place where an electric power supply source is not available. Further, the digital audio tape recorder 1 has operation members 2A - 2G such as an eject button, a playback button, a record button, a fast-forward button, a rewind button and so on arranged in its upper front portion, and its operation mode is adapted to be changed over by manipulating these operation members 2A - 2G. Furthermore, the digital audio tape recorder 1 has an electric power source switch 4, an earphone jack 6, volume control and recording level control operation members 8, 10 and so on arranged in its front surface, whereby the operation members to be frequently used are concentrically disposed in the upper front portion and the front surface. That is, the digital audio tape recorder 1 has changeover switches 12, 14 for changing it over to the input mode and the recording mode whose frequencies in use are relatively low, disposed in its side together with a microphone input terminal 16 and so on. Thereby, the digital audio tape recorder 1 can be made small in size as well as designed to effectively avoid a degradation of its operability by making effective use of a correspondingly small-sized region where the operation members and the like can be arranged. The upper side of the digital audio tape recorder 1 is covered by a lid 20 pivotally supported thereby, and the lid 20 is adapted to be opened by operatively pushing the eject button 2A. That is, the lid 20 is fixedly secured to threaded holes 22A, 22B of a cassette holder 22 by means of screws and adapted to be pivoted interlockingly with a pivotal movement of the cassette holder 22. The cassette holder 22 is mounted by threadably securing an upper plate 26 to a lower plate 24 having the ]-shaped cross-section by means of screws 26A, 26B. When it is pivoted after the cassette has been accommodated within a region defined as a rectangular configuration surrounded by the upper plate 26 and the lower plate 24, the cassette is mounted in place. Thereupon, as shown in FIG. 2, the cassette holder 22 is adapted to press the cassette toward the side of the lower plate 24 through cassette pressing members 28A, 28B arranged in the opposite sides of the upper plate 26, whereby the cassette is adapted to be held in place. That is, the upper plate 26 has column -like projections 30A, 30B formed by being punched out from the side of the lower plate 24 as well as has a pressing portion 31 and a window 32 for each of the cassette pressing members 28A, 28B, formed in order in its deep portion behind the projections 30A, 30B. The pressing portion 31 is formed by cutting over the upper plate 26 and bending the cut piece and serves to hold the cassette pressing member 28A, 28B therebetween. On the other hand, the cassette pressing member 28A, 28B is formed from a spring member and has through-boles 34A, 34B cut out corresponding to the projections 30A, 30B. Thereby, the cassette pressing member 28A, 28B can be secured simply and with high accuracy at the projection 30A, 30B by fitting the through holes 34A, 34B to the projections 30A, 30B after having been so brought as to be caught in the pressing portion 31 as indicated by the arrows. Further, thereupon, since the cassette pressing members 28A, 28B can be held in simple construction by holding the cassette pressing members 28A, 28B in such a manner as being caught in the pressing portion 31, the digital audio tape recorder 1 can be simplified in construction as well as have the cassette holder 22 thinned in entire thickness. Further, the cassette pressing members 28A, 28B have a triangular pressing portion 36 at their leading ends respectively, and the pressing members 36 serve to press down the tape cassette through the window 32. That is, as indicated by the broken line in FIG. 3, the pressing portions 36 serve to press predetermined upper left and right regions 42A, 42B of the tape cassette 40 by being resiliently urged by the cassette pressing members 28A, 28B. Thereby, the cassette pressing members 28A, 28B press the tape cassette 40 so as to push it to the lower plate 24, so that the tape cassette 40 is held in place. On the other hand, similarly a cassette pressing member 44 formed from a spring-like member is fixedly secured to the central deep portion of the upper plate 26 by making use of eyelets. That is, the cassette pressing member 44 has an extended central portion, which is provided at its leading end with a triangular projecting pressing portion (not illustrated). Further, the cassette pressing member 44 has opposite ends extended left and right, whose leading ends are fixedly secured to the upper plate 26 by means of the eyelets. By securing the cassette pressing member 44 through the eyelets in that way, the cassette pressing member 44 can be fixedly secured to the upper plate 26 in a simple construction as well as the cassette holder 22 can be made thin in entire thickness. The upper plate 26 is provided with a window formed therein corresponding to the pressing portion of the cassette pressing member 44. Thereby, the pressing portion of the cassette pressing member 44 serves to press the tape cassette 40 through the window. Accordingly, the cassette pressing member 44 presses the concave portion 46 of the tape cassette 40 through its pressing portion, so that the tape cassette 40 is held in place as well as pressed toward the side of the lower plate 24. A display panel 47 is disposed between the cassette holder 22 and the lid 20, so that the operation modes of the digital audio tape recorder 1, a residual amount of the tape in the tape cassette 40 and so on can be confirmed through the display panel 47. That is, the display panel 47 is made by disposing a liquid crystal display panel as shown in FIG. 4 onto a plate-like luminous element composed of an EL (an electroluminescence) and interposed between the lid 20 and the upper plate 26 except the cassette pressing members 28A, 28B, 44. Incidentally, the liquid crystal display panel comprises a display portion 50 for displaying a tape residual amount, a play time and so on, a display portion 51 for program numbers, a display portion 52 for a signal level and a display portion 53 for displaying a playback operation and the like. Corresponding thereto the lid 20 has the window 48 formed above the display panel 47, and the window 48 is covered by a transparent member 49 from inside of the lid 20. Thereby, a user can confirm the tape residual amount and the like through the window 48, so that the use convenience of the digital audio tape recorder 1 can be improved by that. Thereupon, since the display panel 47 is interposed between the lid 20 and the cassette holder 22, the display portions can be formed by making effective use of the upper surface of the digital audio tape recorder 1. Accordingly, the digital audio tape recorder 1 can be made smaller in size by that without sacrificing its operability. Further, thereupon, since the display panel 47 is interposed in the space defined between the lid 20 and the upper plate 26 excluding the cassette pressing member 28A, 28B, 44, it becomes possible to insert the display panel 47 into a small space defined between the lid 20 and the upper plate 26. Accordingly, since it is possible to accommodate the display panel by making effective use of the space between the lid 20 and the upper plate 26, the lid 20 and the cassette holder 22 can be reduced in thickness by that correspondingly so that the entirely thinned and small-sized digital audio tape recorder 1 can be provided. According to the above-mentioned construction, since the display panel 47 is interposed between the lid 20 and the upper plate 26 excluding the cassette pressing members 28A, 28B, 44, the display panel 47 can be so disposed as to make effective use of the space defined between the lid 20 and the upper plate 26. Thereby, since the display portions can be formed by making effective use of the upper surface of the digital audio tape recorder 1, the digital audio tape recorder 1 can be made smaller and thinner in dimension by that effective use without sacrificing its operability. Incidentally, though the above-mentioned embodiment has explained the lid 20 and the holder 22 which are adapted to be provided, the present invention is not-limited to that but it is also widely applicable to, for example vertically liftable ones. Further, though the above-mentioned embodiment has explained the case in which the present invention was applied to the portable digital audio tape recorder, the present invention is not limited to that but it is also applicable to a stationary digital audio tape recorder. Further, the present invention is not only applicable to the digital audio tape recorder but also widely applicable to a recording and/or reproducing apparatus which records and playbacks various kinds of signals such as an audio signal, a digital signal and so on. As noted above, according to the present invention, since a display panel is disposed at such a position as not to face a cassette pressing member between a lid and a holder, it becomes possible to provide display portions by making effective use of a space defined between the lid and the holder. Thereby, it is possible to provide the display portions by making effective use of the upper surface of the lid as well as it is possible to achieve a correspondingly small-sized and thinned type recording and/or reproducing apparatus which is equipped with the display portions.
