Problems solved by technology
[0002] The current printing clock will leave time records on documents or other papers through the action of the control circuit. It has the defect of complex circuits, and it must hit the printing ribbon through precision parts such as the printing head through the dot pins and strikers, so that it can be printed on the documents or other papers. The printing effect is produced on the paper card, which is not only inconvenient to maintain, but also relatively high in manufacturing and use costs

Embodiment Construction
[0018] Depend on figure 1 It can be seen that the 1r / min synchronous motor 2 placed at one end of the main frame 1 of the printing clock will pass the cam 3 at the end of the output shaft of the synchronous motor, so that the lever mechanism 4 will move the minute character wheel 5 forward by one step per minute, and the minute character wheel will be single. The function of the rod 6 is to prevent the minute character wheel 5 from reversing; when the minute character wheel 5 that advances one grid per minute enters the 00 minute grid from the 59 minute grid, the hour character wheel 8 is driven forward by the minute hour character wheel ratchet 7 One grid, the hour character wheel 8 also has a one-way lever for the hour character wheel to prevent it from reversing; when the hour character wheel 8 advances one grid every 60 minutes, it is controlled by the cam on the hour character wheel and the rocker arm when it advances from the 23 hour grid to the 00 hour grid The rod mech...

The invention discloses a simple printing clock. The simple printing clock comprises a travel time mechanism and a manual printing mechanism which are driven by a sync motor, and the rotating speed of the sync motor is 1r / min. A cam on the tail of the output shaft of the sync motor drives a minute print wheel to advance one grid per minute via a driving lever mechanism; when the minute print wheel advances from the 59-minite grid to the 00-minute grid, a minute / hour print wheel pallet drives an hour print wheel to advance one grid; when the hour print wheel, which advances one grid per 60 minutes, advances from the 23-hour grid to the 00-minute grid, the cam and a rocking lever mechanism on the hour print wheel drive a week print wheel to advance one grid; and after a manual printing mechanism is pressed for certain times, a gear lug bar can drive a round hole ribbon gear and a square hole ribbon gear to rotate one gear simultaneously, and the square hole ribbon gear can drive a ribbon axle to rotate once, so that a ribbon core is enabled to rotate. The printing clock is favorable for users to reduce the production cost and convenient for routine maintenance.
Description
technical field [0001] The invention relates to a simple printing clock. Background technique [0002] The current printing clock will leave time records on documents or other papers through the action of the control circuit. It has the defect of complex circuits, and it must hit the printing ribbon through precision parts such as the printing head through the dot pins and strikers, so that it can be printed on the documents or other papers. The printing effect is produced on the paper card, which is not only inconvenient to maintain, but also has relatively high manufacturing and use costs. Contents of the invention [0003] The purpose of the present invention is to provide a simple printing clock that can overcome the above-mentioned shortcomings, and it does not need a control circuit or a precision printing head. [0004] The so-called simple printing clock of the present invention, it contains travel time mechanism and manual printing mechanism, is characterized in ...
