Title: Paper guide device for printer
Inventor: YUMOTO MAKOTO
IPC: B41J13/14
Filed: 1985-04-20
Abstract: PURPOSE:To enable a paper-guiding function to be increased without interfering with replacement of a printing element or the like, by providing at least one movable guide member which can be moved in the width direction of the paper. CONSTITUTION:The movable guide member 26 is slidden along a paper- discharging guide 24 to such a position that the entire part of a leading end part of a paper can be fed between both guides 24, 25. When the width of the paper 5 is changed, the member 26 is slidden in the direction of arrow F in conformity to the paper width, thereby locating the member 26 at an optimum position for guiding the leading end part of the paper. Since the guide member 26 does not interfere with a printing head 16, operation of a carriage 15 or the head 16 will not be hindered by the member 26. Accordingly, it is possible to securely guide the leading end part of the paper and to prevent the paper from jamming without largely protruding the guide 24 itself.

IPC: F23N5/26
Filed: 1989-04-04
Abstract: PURPOSE:To make it possible for a user to find out a breaking of wire of an ignition heater by detecting the electric current flowing though the ignition heater in starting preheating right after starting the operation and displaying the abnormality by an optical element when the electric current that is passing through the heater is not detected. CONSTITUTION:A microcomputer 12 starts the operation of a combustion device by its manipulation by the user. And right after this its output 14 is put to 'H' and a relay 3 is turned ON. With this an ignition heater 2 is in the state of being energized by electric current and it is in the mode of preheating. When the ignition heater 2 is normal, the A.C., IAC is over IS and the input 13 to the microcomputer 12 detects 'L'. If the ignition heater 2 has a breaking of wire, the A.C., IAC is not generated so that the input 13 to the microcomputer 12 becomes 'H', and the microcomputer 12 judges thereby that an abnormality is in the ignition heater and brings its output 14 to 'L' in order to stop the operation forcibly and puts OFF the relay 3 and the electric current to the ignition heater 2 is stopped, and at the same time by putting the output 18 to 'H' a transistor 9 is turned ON and a LED 20 is lighted. Accordingly the user is able to judge the stopping of the operation in a short time and identify the breaking of wire in the ignition heater.

Filed: 1987-04-09
Abstract: PURPOSE:To make continuous detection of change in the leftover ink quantity by providing a transport means to move a float, an ink tank and a sensor and a detection means to detect a leftover ink quantity in response to a shielding duration of an infrared beam by a light shielding member in the process of said transport. CONSTITUTION:If a carriage 6 moves to a direction (S) toward element 7A, 7B arranged near a home position, infrared beam (L) emitted by a light emitting element 7A is interrupted by a shielding plate 9 in a float and, therefore, is not, received by a light-receiving element 7B at an early stage. If the carriage is further moved to the direction (S), and a slit (9A) of the shielding plate 9 in a float 6 comes to a position where the slit (9A) crosses the optical axis of the infrared beam (L), the infrared beam (L) emitted by the light emitting element (7A) enters the light-receiving element (7B) at this time. In addition, an opposed wall of an ink chamber (3A) in an ink tank 3, at least, a part located in a light path of infrared beam needs to be formed using a material which infrared beam permeates easily, and for this reason, e.g. transparent acrylic sheet is the best choice of use, considering ink resistance.
