Title: Guide shaft for carrier
Inventor: TAKEDA KOICHI
IPC: B41J19/20
Filed: 1984-11-30
Abstract: PURPOSE:To contrive a reduction in load on a driving motor, by a method wherein a guide shaft circular in cross section for guiding a rectilinear reciprocation of a carrier is rotated prior to the movement of the carrier. CONSTITUTION:The guide shaft 11 circular in cross section for guiding the rectilinear reciprocation of the carrier 4 is rotated prior to the movement of the carrier 4. For example, the guide shaft 11 is started rotating prior to the start of the movement of the carrier 4, and the rotation is stopped after the carrier 4 is stopped in response to completion of printing. Thus, the guide shaft 11 is being rotated at the time of the start of the carrier 4 for moving a printing head 3, namely, at the start of the carrier 4 which is repeatedly started and stopped during printing, so that only dynamic frictional resistance is generated and no static frictional resistance is generated at a sliding contact surface of the carrier 4 and the guide shaft 11. Accordingly, load on the carrier against movement is reduce.

Title: Tablet input device
Inventor: MATSUI KOICHI
IPC: G06F3/046
Filed: 1984-11-30
Abstract: PURPOSE:To eliminate the need for provision of an amplifier or the like in the inside of an input pen by detecting a discharge current at electrode line discharge and specifying a command coordinate on a tablet based on the quantity of the discharge current. CONSTITUTION:When the input pen 16 is pressed into contact onto a tablet 1, a pen switch 18 is operated and a signal PSW is fed to a CPU. The CPU responds to it and applies a switch signal CH to a multiplexer MPX to connect sequentially drivers DX1-DX4. Charge/discharge is executed to each electrode line corresponding thereto. In pressing the pen 16 into contact in the vicinity of a group electrode line 4, since the detection tip 17 is grounded, the capacitance to the earth of the electrode line 4 is larger than that of other group electrode lines 2, 3, 5, much electric charge is stored relatively to the electrode line 4 and the signal SS generated at discharge is increased relatively. A CPU discriminates the press contact position of the pen 16 based on the detection signal SS, and this is the same to the other electrode lines 6-15. Thus, the commanded coordinate is specified.
