Title: Driving method for recording head
Inventor: MORIGUCHI HARUHIKO
IPC: B41J2/36
Filed: 1987-01-29
Abstract: PURPOSE:To enable thermal recording at high speed and with high image quality, by varying energization energy to be applied to heat generating elements according to the cumulative number of mark signals and the number of a series of space signals. CONSTITUTION:The cumulative number of mark signals counted by a counter 7a is calculated, the result of calculation is transmitted to a pulse duration calculator 7b to determine a pulse duraction, and a strobe signal is applied to a recording head 5 according to the pulse duration determined. The calculation at the calculator 7b is conducted according to a predetermined calculation table, and a control is performed so that the duration of energizing pulses is reduced as the cumulative number of the mark signals is increased. The reduction ratio may be conformed to a heat generating period, the high-heat characteristics of a head substrate or the like, or may be combined with history correction for each heat generating element. When a continuous printing operation is stopped or space signals or the like are given in series during predetermined recording, the quantity of heat accumulated in the head substrate 5a or the like is reduced due to heat release, and in this consideration, printing is performed by recovering the reduced pulse duration again to a great value according to the situation.

Title: Mechanism for opening/closing paper presser lever
Inventor: MURAKAMI KENJIRO
IPC: B41J13/10
Filed: 1988-01-28
Abstract: PURPOSE:To hold a paper presser assembly constantly stably, by opening/closing a paper presser lever assembly holding the paper presser assembly using a motor for feeding a printing paper. CONSTITUTION:Usually, a paper presser shaft 8 is depressed down against a platen 3 by springs 9, 10 to be held stably. A gear 14 is disengaged from a gear 15 by a spring 21, whereby a lever 11 fails to act even if a platen gear 3a rotates. The electric conduction to a solenoid causes a trigger board 18 to be attracted, thereby moving the gear 14 along a guide groove 18a to a position on which it can engage with the gear 15. The drive force of a paper feed motor is transmitted to the gear 15 and a gear 16, but the gear 16 only rotates without engagement. The gear 15 rotates the lever 11 in a direction A so that a guide surface 11a comes into contact with a shaft 12, and rotates a lever 6 until a part 6a thereof comes into contact with a projected part 1a of a frame. At this time, the electric conduction to the solenoid is cut, and the paper presser shaft 8 is held stably. On the contrary, the travel in a direction B reverses the situations of the gear 15 and the gear 16.

Thus, an excellent characteristic both slide noise and wear resistance is obtained.

Title: Magnetic recording medium
Inventor: SOMEZAWA MASASHI
IPC: C09D175/04
Filed: 1988-01-29
Abstract: PURPOSE:To improve electromagnetic conversion characteristics and durability by incorporating a resin having a basic polar group into a binder and polyvalent carboxylic acid and the anhydride thereof into a magnetic layer. CONSTITUTION:The magnetic layer 2 essentially consisting of the magnetic powder and binder is provided on a nonmagnetic base 1 and the resin having the basic polar group is incorporated into the binder. The polyvalent carboxylic acid and the anhydride thereof is incorporated into the magnetic layer 2. The polyvalent carboxylic acid, therefore, interposes between the binder and the magnetic powder to well bond both and since the surface of the magnetic powder is coated with the proton-donating acid groups, the adsorption of various additives such as lubricant having proton-donating atomic groups and dispersant on said powder is hindered. The coated film is thereby perfected without losing the dispersion stability of the magnetic powder and the boundary face reinforcing property of the binder. The magnetic recording medium having the excellent electromagnetic conversion characteristics and durability is thus obtd.
