A conveying direction switching apparatus includes a first and a second blade assembly, and auxiliary blades rotatably provided at a shaft. The auxiliary blades are arranged between the first and second blade assemblies. When conveying bills, the portions of the bills passing between the first and second blade assemblies in the longitudinal direction of the shaft are guided by the auxiliary blades toward the conveying direction of the bills. Thus, the conveying direction of the medium is appropriately switched.

To provide a medium storing and advancing apparatus which orderly piles up bills even when not flat. The medium storing and advancing apparatus includes a tongue piece roller having tongue pieces having the length thereof predetermined. While the tongue piece roller is rotated to slap the rear end of a bill with the tongue pieces to orient the latter downward, the front end of a following bill is superimposed on the downward-oriented rear end of the preceding bill.

A video format signal recording and reproducing method wherein a plurality of division video signals are obtained by dividing a single video format signal and are recorded onto a plurality of recording media, set indication ID numbers are recorded. When the division video signals are reproduced from the recording media, the set indication ID numbers are automatically discriminated. Only when the set indication ID numbers coincide each other, the reproducing operation of the single video format signal is executed.

A medium accumulating device has an accumulation table on which a medium is accumulated, an elastic member that supports the accumulation table, and an accumulation table detector that detects lowering of the accumulation table. It is sensed that the accumulation table inclined with respect to a lifting and lowering direction of the accumulation table lowers below a predetermined position to thereby determine whether or not a medium is accumulated on the accumulation table. This provides the medium accumulating device capable of determining whether or not a medium is accumulated whatever position the accumulation table may occupy.
