A manually actuated self-collecting parking meter includes a single lockable coin insertion device for receiving a range of available coin diameters. A coin checking device is arranged to receive one coin at a time from the insertion device and is placed in operation by turning a rotary locking handle. A parking time period display mechanism is arranged to be set based on the coin inserted into the checking device when the handle is rotated. The rotary locking handle can be rotated in either direction up to a stop for loading a force accumulator which automatically drives an operating mechanism for effecting the operation of the coin checking device and the setting of the display mechanism. For proper phase control of the operating mechanism, a closing segment and an operating segment are provided which uncouple the operating mechanism when the rotary handle is completely rotated so that the automatic operation is carried out.

A preselection counter having a switch-off counter which is adapted to actuate a desired function when a quantity of this function determined by a preset value has been reached includes presettable indicating means having number rollers adapted to have the preset value set therein and to retain this setting through repeated cycles of operation of the switch-off counter. The presettable indicating means enable continuous display of the preset value during operation of the counter with the preset value being transferred from the number rollers of the switch-off counter by a sensing wheel mechanism which is operatively interposed therebetween and which may be repeatedly reset to the preset value on the preset counter after each cycle of operation of the switch-off counter without requiring changes in the preset value in the presettable indicating means.

In a setting device for presettable counters, a number of indicating rollers are arranged with symbols on their circumferential peripheral surfaces. Connected to each indicating roller is a ratchet wheel and an adjusting wheel. A switching device for each roller permits it to be moved in a step-by-step manner and otherwise to be locked in position. The switching device includes a switching pawl for engaging the ratchet wheel and moving the roller, a fixing lever for locking the adjusting wheel and roller in position, a control pawl and a key for displacing the control pawl. The control pawl is spring-biased against the actuating movement of the key. The control pawl displaces the switching pawl and the fixing lever in response to its displacement by the key.
