of the sheet bundle, and determine that the press processing is not to be performed on the sheet bundle, when the number of
sheets of the sheet bundle is less than the threshold value,

wherein the threshold value is determined based on the number of sheets of the sheet bundle at which a stack processing time
required for said stacking unit to form the sheet bundle does not become larger than a press processing time required for

POWER SUPPLY AND IMAGE FORMING APPARATUS

CANON KABUSHIKI KAISHA, ...

1. A power supply comprising:
a transformer having a primary side and a secondary side which are insulated with each other;
a first switching element configured to perform a switching operation of switching between an ON state in which a voltage
is supplied to the primary side of the transformer and an OFF state in which the voltage is prevented from being supplied
to the primary side of the transformer;

a second switching element connected to the secondary side of the transformer, configured to switch between the ON state and
the OFF state wherein the second switching element is turned off in a case where the first switching element is turned on,
and turned on in a case where the first switching element is turned off; and

a control unit configured to control the switching frequency of the first switching element so that an output voltage of the
secondary side of the transformer becomes a predetermined voltage; and

a delay unit configured to delay a timing to turn off the second switching element off by a signal output from the control
unit so that a period when the second switching element is turned on in a low load condition is longer than a period when
the second switching element is turned on in a normal load condition, wherein a current supplied to the load from the secondary
side of the transformer in the low load condition is smaller than a current supplied to the load from the secondary side of
the transformer in the normal load condition.

CONTROL METHOD FOR ROBOT APPARATUS AND ROBOT APPARATUS

Canon Kabushiki Kaisha, ...

1. A control method for a robot apparatus including
a power supply unit;
an articulated arm having a plurality of joints each having an actuator and a driver configured to adjust power of the power
supply unit and supply it to the actuator; and

a control device configured to control the driver such that power required for an operation of the actuator may be supplied
from the power supply unit to the actuator to move a position/attitude of the articulated arm, the method comprising:

determining by the control device whether a total of required power in all of the actuators is equal to or lower than an allowable
power of the power supply unit by using a trajectory through teaching points for moving the articulated arm from a first position/attitude
to a second position/attitude before the articulated arm starts moving; and

if the total of required power in all of the actuators is higher than the allowable power of the power supply unit, resetting
by the control device the trajectory for moving the articulated arm from the first position/attitude to the second position/attitude
to a trajectory causing a total of required powers in all of the actuators to be equal to or lower than the allowable power
of the power supply unit.
