Title: Mechanism for automatically adjusting head pressure of thermal printer
Inventor: BESSHO KAZUYA
IPC: B41J25/316
Filed: 1991-10-25
Abstract: PURPOSE:To prevent a printing from becoming thick by temp. rise by reducing the pressure of a thermal head when the temp. of the thermal head rises. CONSTITUTION:A pressure adjusting element 6 is arranged so that the small driving quantity thereof is transmitted while amplified at the support point of a spring 4. At the point of time when the intensity of the detection signal from a temp. sensor 2 exceeds a set value, for example, when a vertical line continues, the mean temp. of the thermal head 1 rises from normal temp. because the heat value thereof increases. At this point of time, a control signal is sent to a high voltage generating circuit 8. The circuit 8 applies high voltage to the pressure adjusting element 6 on the basis of the control signal to shorten the pressure adjusting element 6 and the pressure of the thermal head 1 is reduced to normally correct printing thickness.

Title: Battery device
Inventor: NAKAZAWA RIYOUYA
IPC: H01M50/528
Filed: 1992-10-23
Abstract: PURPOSE:To enlarge a using range of a power source and prevent a damage to equipment due to erroneous connection by covering a terminal for a low voltage with a slide cover at the time of a high voltage output in a device provided with connector terminals for a high and a low voltage. CONSTITUTION:A battery device main body 1 comprises a connector terminal 4 for a low voltage output, a connector terminal 5 for a high voltage output, and a slide cover 2 capable of sliding between a position where the terminal 4 is closed and a position where the terminal 4 is opened. A switch lever 3 is disposed in the cover 2 so that a voltage changeover switch is changed over onto a low voltage side when the cover 2 is slid and the terminal 4 is opened while onto a high voltage side when the terminal 4 is closed. Accordingly, since the terminal 4 is closed when the switch is positioned on the a high voltage side, erroneous connection of low voltage equipment can be prevented. Although the terminal 5 also is located on a low voltage side when the switch is positioned on the low voltage side, a damage can be prevented even if high voltage equipment is erroneously connected to the terminal 5. Consequently, a voltage converting converter becomes unnecessary, and a damage to the equipment due to erroneous connection can be prevented.

Near the holder 43, there is a terminal metal fitting 50 which is used as a contact part of a switch just like the holder 43 and is electrically connected to a current path which runs in an armature 25. A protective switching means 47 is installed to electrically connect the holder 43 when the holder is at a specified temperature or below and disconnect the holder 43 when the holder is at the specified temperature or above. By this method, the burning of the brush 44 caused by an abnormal spark is prevented.
