Abstract

PURPOSE:To progress an automation in the handling of a paper to simplify the operation of a printer, by automating the operation of a release lever. CONSTITUTION:When a solenoid 12 is electrically conducted and a trigger board 11 is attracted, a planetary lever 8 is detached from a held state. After that, the power of a stepping motor 14 rotates a gear 10 in a direction of an arrow A through a gear 15, whereby a planetary gear 9 engages with the gear part of a release lever 2. Then, the lever 2 rotates to be fixed by an auxiliary lever 3. At this time, the trigger board 11 is restored, the planetary lever 8 is also returned to a neutral position, and the planetary gear 9 is also detached from the lever 2 to be in a release state to allow the insertion of a paper. To be restored from the release state, the planetary gear 9 is engaged with the lever 2, a motor 14 is reversely rotated, and thereafter an action similar to that for making a release state is carried out.

転力を歯車（図示せず）を介して伝達される。FIG. 1 shows an embodiment of the present invention, and reference numeral 1 in the figure indicates a printer main body. A release lever 2 and a release auxiliary lever 3 are pivotally supported on the inner side of the insertion side, and the release lever 2 and the release auxiliary lever 3 mutually form a cam shape. The release auxiliary lever 3 is engaged with a paper feed roller shaft 6 that is fitted into a paper feed roller holder 5 that is engaged with a paper feed roller 4 . The paper feed roller 4 is normally in pressure contact with the platen 7, but can be released by operating the release lever 2. A toothed portion that meshes with the planetary gear 9 is formed at the broken line portion a of the release lever 2 . The planetary lever 8 is pivotally supported by the main body, and two planetary gears 9 are pivotally supported on the planetary lever 8. A release transmission gear 10 disposed coaxially with the planetary lever 8 is engaged with the planetary gear 9. Further, the release transmission gear 10 is coaxially supported with the platen 7, or the rotational force from the platen is transmitted via a gear (not shown).

ー８は中立位置に復帰する。The trigger plate 11 normally engages with the planetary lever 8 to keep the planetary lever 8 at a neutral position, and when the suction force of the solenoid 12 is applied, the planetary lever freely rotates and the toothed part 9 of the release lever and a planetary gear supported by a planetary lever. When the suction force of the solenoid 12 is cut off, the trigger plate is arranged to return to a predetermined position by the action of the trigger plate return spring 13, and at the same time, the planetary lever 8 returns to the neutral position.

遊星歯車９もレリースレバー２から離脱する。First, the operation of switching the paper feed roller 4 to the released state will be described. The solenoid 12 is energized to generate an attractive force to attract the trigger plate 11 and rotate it in the direction of arrow A. At this time, the planetary lever 5 is released from the holding state. Next, the power of the stepping motor 16 is transmitted to the platen gear 15 and then to the release transmission gear 10, and when the release transmission gear IO rotates in the direction of arrow A around the rotation center B, it is pivotally supported by the planetary lever 8. The planetary gear 9 engaged with the gear portion of the release lever 2. In this way, the power of the motor is transmitted, the release lever 2 rotates, stops at a predetermined position, and is fixed by the release auxiliary lever 3. At this time, the power to the solenoid 12 is cut off, the trigger plate 11 returns to the predetermined position by the action of the trigger return spring 13, and the planetary lever 8 simultaneously returns to the neutral position by the action of the trigger plate 12, and the planetary gear 9 naturally also separates from release lever 2.

以上のような動作をして、レリース状態となり連続伝票
用紙の挿入が可能となる。By performing the above-described operations, the printer enters the released state and can insert continuous slip forms.

次に、レリース状態から脱する場合の動作について述べ

様である。The operation until the planetary gear 9 engages with the release lever 2 is similar to the operation when the release lever 6 is placed in the released state. Thereafter, the stepping motor 14 rotates in the opposite direction, and when the release transmission gear 10 rotates in the direction of arrow B, the release lever 6 returns to the predetermined position. After this, the operation until the planetary gear 9 is disengaged from the release lever 6 is the same as the operation when the release lever 6 is brought into the released state.
